TORONTO - Brian Dickson’s voice rose as he denied killing Xian “Necole” Liu to police in an audiotaped interview played at his murder trial Thursday.

“No, I did not. I had nothing at all to do with it,” snapped Dickson at Toronto Police Det.-Sgt. Frank Skubic on April 19, 2011. “Yes, I understand why you had to ask, and if I were you, I’d ask.”

Dickson, 32, has pleaded not guilty to first-degree murder in the April 15, 2011 death of the 23-year-old York University student and fellow tenant. Dickson earlier tried to plead guilty to manslaughter but the prosecution rejected the plea.
